WIND SHIELD WEATHER STRIP.

` Application filed June 23, 1924. Serial No. 721,796,

` IThis invention relates to automobile windshields, and has ior an obJect the use o a v liat strip ot rubber or the equivalent as a lll weatherstrip, by forming the windshield trame member with a channel which 1s sharply bent in cross-section, so that thev strip is held lirmly by its own resilience on account ot' the distortion caused by the peculiar shape oi. the channel. Preferably the -trame member is a hollow metal tube with the channel along one edge.

rlhis and other desirable features will be apparent 'from the 'following description of one illustrative embodiment ot the invention shown in the accompanying drawings, in which:

Figure 1 is a side elevation of a windshield, and an associated visor and windshield wing;

Figure 2 is a iront elevation of the same parts;

Figure 3 is a section on the line 3--3 of .l i gure 2., showing part or' the sealing means;

Figure 4 is a section on the line 1--11 of Figure 2, showing one weatherstrip in its channel;

Figure 5 is a section on the line 5-5 oi Figure 2, showing another weatherstrip in its channel; and

Figure 6 is a section on the line 6-6 of Figure 2, showing the joint between the upper and lower glass panes of the windshield.

rllhe invention is shown embodied in a windshield comprising side stanchions 10 arranged to be secured to the cowl of an automobile by bolts 1Q, and carrying a lower lined pane 14 of glass held on three edges by a 'iframe 16 of hollow metal tubing, and an upper movable pane 18 of glass held on three edges by a trame 2O et hollow metal tubing pivoted at 22 on the stanchions. The space between the panes, when the windshield is closed, is sealed by a U-shaped strip 24 of rubber straddling the lower pane 14:. A windshield wing 26 is held by a lower bracket 28 and by an upper bracket 30 secured by tap screws 32 which also hold one bracket 34E of the visor 36. Each pane le and 1S is seated in channels formed in the edges of the hollow tube members of the frames 16 and 20, cushioned if desired by strips 38 of felt or the like. Each side member of the trame 16 carries a rubber iilling piece 40 concaved to embrace tightly and seal against the corresponding stanchion 10. Below the bottom edge ot the bottom member oi frame 16, the filling pieces 40 project into engagement with the cowl, and on their inner sides are grooved at Ll2 (Figure 3).

The bottom member of frame 16 is also provided on its lower edge with a reentrant channel., having a sharp bend in cross-section shown in Figure 4, 'for a sealing strip 50 et rubber or the like. Thus the strip 50 may be substantially rectangular in crosssection, since it is held in place by its own inherent resilience due to the sharp bend in the channel, and this permits extending the strip into the grooves l2 (Figure 3), thus sealing the entire lower edge of the windshield.

Each side member o1 the frame 2() is provided on its outer edge with a reentrant channel, shown as forming a right angle in cross section, `lor a sealing strip engaging the corresponding stanchion 10. Thus each strip 60 may also be substantially rectangular in cross-section, Since it is held by its own distortion, and may in fact be cut from the same length of stock as strip 50.

hile one particular windshield construction has been described in detail, it is not my intention to limit the scope of' the invention to that construction, or otherwise than by the terms of the appended claims.

I claim:

1. A windshield part comprising, in combination, a hollow metal tube member having a channel along one edge for a pane of glass and having a sharply-bent reentrant channel o'l' uniform width along its opposite edge, and a rubber strip ot unii'orm thickness throughout and ot substantially reetangular cross-section held along one edge of the reentrant channel and retained in the channel by reason of its elasticity.

2. A windshield part comprising, in combination, a frame member having along one edge a reentrant channel oii uniform width throughout its extent, the channel having in cross section a sharp bend, and a rubber strip held along one edge in the channel by its inherent resilience as it is held distorted by said bend, said edge within the channel corresponding in thickness with the uniform width of the channel.

3. The combination of a body part, a. windshield mounted in operative relation with said body part and comprising a frame member having aehannel therein for receiving a pane of glass, and a second channel therein having sides and a bottom member, Said sides being substantially parallel but distorted to provide a tortuous chamlelyand.

a fiat strip of rubber gripped in said channel and distorted thereby to hold it against dislodgment, said strip proiecting outwardly from the frame into contactwith said bo part whereby said strip is distorted into elose'iitti'ngl and sealing relation with said body art. M 1L Fhe combination of' a body part, upright stanchions carried thereby, a windshield monnted onsaid stanchion in operative relation with said body part, and including a frame member pivoted to said LLOYD BLACMOR'E.
